Late Model Chassis Under 67-72 Sheetmetal??

[72longbed]

Question for you 4x4 Experts:
What later model, (after 72), 4x4 chassis' will work with 72 Cab and sheetmetal?? Are there some years that are less work to retrofit than others? What late model chassis are better for an 8ft 72 bed and all other sheetmetal??

Just like to get all the latest, 'hot lick', type info before I start my very serious search for a 4x4 rolling chassis.

Thanks for your opinions and experience,
